Perhaps you should try some spelling variations:
"based sorting algorithms" » "based routing algorithm" (Expand Search), "based learning algorithms" (Expand Search), "based scoring algorithms" (Expand Search), "based testing algorithms" (Expand Search), "based dosing algorithms" (Expand Search)
"data making algorithm" » "data learning algorithm" (Expand Search), "data finding algorithm" (Expand Search), "data means algorithm" (Expand Search), "data backing algorithm" (Expand Search), "data mining algorithm" (Expand Search), "data tracking algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("data making algorithm") OR ("based sorting algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data making algorithm\") OR (\"based sorting algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data making algorithm ) OR ( based sorting algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data making algorithm") OR ("based sorting algorithms"))) OR ("element method algorithm"))*.
